Cross-linked polyethylene insulated power cables (XLPE cables), with rated voltages of 3.6/6kV–26/35kV, are core products for medium- and high-voltage power transmission and distribution systems. These cables utilize high-quality copper or aluminum conductors and a cross-linked polyethylene insulation layer, boasting excellent dielectric and heat resistance. They operate at temperatures up to 90°C and can withstand thermal shocks up to 250°C during short circuits. They offer low insulation loss, high current carrying capacity, and stable electrical performance, meeting the requirements for safe power transmission across various voltage levels.
Mechanically, these cables exhibit high tensile strength, bending resistance, and abrasion resistance, offering flexible installation options for underground, cable trench, tunnel, or overhead installation. The cross-linked polyethylene insulation layer is oil-free, eliminating the risk of oil leakage, making it environmentally friendly and maintenance-free. Compared to traditional oil-impregnated paper-insulated cables, these cables offer increased safety, reliability, and transmission efficiency, with a service life exceeding 30 years. With its efficient transmission, safety, reliability, environmental protection and durability, this series of cables is widely used in urban power grids, power distribution in industrial and mining enterprises, substation projects and important infrastructure construction.
